-WILLIAM G. BL EY, on CINCINNATI, OHIO.

To all whom it may concern:

Be it known that'I WILLIAM G. BLEY, a

"citizen of the United states, residingiat Cincinnati,'in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Means for Packing Stuffing-Boxes, of which the following is a specification, reference being had'to the accomp anying drawings. This inventionrelates to means for packing stuffing boxes, and particularly to means for packing the stuffing boxes of valvestor like devices, wherein, if thepacking be defective, steam, or other fluid, under pressure, will escape around the valve stem or will escape if the gland through which the valve stem passes be removed for re-stufling the packing.

necessity of shutting the valveor cutting off the supply of fluid under pressure, and this is the main object of my invention. A further object is to provide in connection with the stufiing box, avalve body open- I ing into the stufiing box and provided with a valve, which may be turned to cut off communication through the bore of the valve body or permit passage through said bore and provide in connection with the valve body, a detachable barrel in which a plunger operates, which barrel may be filled with packing attached-to the valve body and then the plunger operated to force the packing into thegland, the valvebeing opened to permit the passage of the plunger 7 I and packing, and closed when the plunger i "sired to repack the valve.

' Application filed May 24., 1916. Serial no. 9 9,637.

A further object is to provide a device of this character, which is very simple in construction, cheaply made, and which may be very readily operated. v

The invention is illustrated in the accom- F lgure 1 is a longitudinal sectional view of the, device attached to the stufling box; Fig. 2jis a side elevation of the barrel ,with detached endviews;

I Fig.j 3 is a side elevation of the plunger with detached end views.

The stufling box5 has one of its walls provided with a transverse hole which is screw-threaded at 6. It is preferred tobore this hole substantially mid-way ofthe ends of thebox so that the portions around the rod 7' may be reached. g

Coacting with the stuffing box 5'is a valve body 9 having a longitudinally extending bore, passage through which is controlled by a rotatable valve 10 which may be in the form of a barrel valve or turncock, held in place by theusualnut 11 and having a handle 12. This bar'rel 10 has a diametrically extending passage 13 which in one 7 position of the valve'is adapted to register with the bore of the valve body 9. 7

One end of the valve body 9 has a tapered screw-threadedhead 14 adaptedto engage in the tapering screw-threaded opening 6 in the wall of the stuffing box. The valve body is also provided with the shoulder 15 to bear against the stufling box. At its opposite. end the valve body is formed with a head 16 exteriorly screw-threaded as at with a central recess 18.

Engaging the screw threads 17 is a coupling 19 having an. inturned flange 20. Coacting with the valve body 9 and with the coupling 19 is a barrel 21 which has a longitudinally extending bore. The forwardportion of this bore is relativelyvreduced in diameter and the rear portion of the bore isscrew-threaded as at 27. ,The

17 and the end face of this head is formed forward end of the barrelhas a reduced portion 22 adapted to be inserted within the recessj-lS and rearward of this reduced portion the barrel is formed with the outwardly extending(flange 2a adapted tobe" engaged by the inwardly turned flange 20 of the coil fit the enlarged portion of the bore. of. the

barrel and screw-threaded as at 28 to engage the serewethreads 27. The forward portion of the plunger is reduced in chaineter and fits snugly the forward portion of the barr l a d th ape t e. 13 in: the valve l0 f he al e bo y'- At i s ear end t is plunger is provided with an annular flange 29 and with a many sided head 30; whereby a W en h may be pp ed.

In the practical operation of this inventi i Will be und rs ood th th valve o y is o dinar ly earried by th stufling box. 5 he ma e i ustr t d and for a permanent part of this stuffing box. The barrel 21, with the plunger, may or may not be normally attached to the valve body Qrdinarily,-however, it will not be so attached, Normally the valve 10 is turned (SO as to close the passage through the bore of hea e bo y Ne hen t e pa k ng Wi hi t t ffing b bec m s d fec iv and it is desired to repack the stuifing box, the plunge is Withdrawn to its .f ll extent from the barrel 2l and the forward pOr-tiQl of the barrel 21 is filled with packing. The

barrel 21 is then connected to the valve body 9, by means, of the coupling 19, andthen the valve 10 is opened. It will be seen that no press r a ape for th reason. tha the plunger 31 fully fills the bore ofthe valv body a d h for ard, po i of the barrel so. that the barrel 10 may beopened with mpunity.v When the. valve. 1. is opened the plunger is rq iltedto' force the pe king in front of. the p unger forwar I into the striding-box and when the stuffing box has been fully repacked, the valve 10 is rotated to close the passage through the valve body, thus again holding the pressure, it being, of course, understood that the plunge s W hdr wn bef e the alve i closed. The packing which is used may be of any suitable character as, for instance, shredded metallic packing or asbestos wick. After the valve 10 has been turned the barrel 1. may b r eased f o ts engagement with the valve body and-the barrel Qldand the plunger may be used iorrepaek ng another valve or th ba rel2l d its plunger ay be kept upon the valve body with the for ward end of the barrel filled with packing and then the packing may be forced into the tnfl ng bo fr m t me to. ime as n cessi y require n i a il ev packing within the barel has b n exhauste mhen he lve. may be turned to closethe passage from the valve body and the barrel 21 be again filled with packing.

Minor changes in the form and details of construction may be resorted to without departing from the spirit of my invention or the scope of the appended claims.

I laving described thisinvention, what is claimed is 1. The combination with a stuffing box, of a valve body having a bore extending into .thetstufiing boX, a valve controlling passagethrough said bore, a barrel having fluid-tight engagement with the end of the valve body, and a plunger operating within the barrel and having its forward end formed to fit and pass through the bore of the valve body when the valve is turned. to open passage through the body.

2(The combination with a StUfiElII bOX, ofa valve body having a longitudinally 6X- tending bore opening into the stufiing box and having an apertured valve shiftableto establish or cut off communicationthrough said bore, a barrel detachably engaged with the uter end of the valve body, and a plunger mounted in saidbarrel and having its forward end formed to'fit thebore or the valve body and the aperture in the valve.
